Abstact The article presents the results of studies of drying of organic-mineral fertilizer. Drying options in various technological regimes are considered. Vacuum methods are used in drying materials because they provide good quality at high speeds. In this study, samples of organic-mineral fertilizers were dried at an absolute pressure of 65-75 Pa at a temperature of 50-70 ° C to assess the drying characteristics. The change in the mass proportion of water can be considered as one of the indicators of the effectiveness of vacuum drying of organic-mineral fertilizer. Optimal drying parameters were established when using a vacuum pump in a laboratory installation. The advantages of vacuum drying are revealed, consisting in reducing the process time by more than 2 times. The proposed model effectively predicts the moisture content in organic-mineral fertilizer during vacuum drying.

This paper aims to analyze effective approaches to waste management in agro-industrial cluster. It considers the studies confirming the relevance and importance of the development of technologies for processing and recycling of waste from the agro-industrial cluster, and, in particular, waste from pig farms. The methods of system analysis, information synthesis, statistical data analysis were used to identify the existing problems. The period from 2000 to 2020 was considered. The most popular directions and production branches have been identified. Quantitative analysis of scientific works on recycling and disposal of waste of agro-industrial cluster was carried out. Based on the data obtained, graphs were built, comparisons were made, conclusions were drawn about the demand for the development of resource-saving technologies, and waste recycling. Based on the analysis of the existing approaches, the authors proposed a cluster form of organization and waste management.

“…The results of studies [11] indicated that the use of manure is a viable strategy for regulating crop yields due to increased soil fertility. The authors of the article have developed methods for obtaining organic mineral fertilizers based on liquid waste from pig farms [12][13][14]. In 2019, the effectiveness of organic mineral fertilizer was evaluated at the D. N. Pryanishnikov Scientific Research Institute of Agrochemistry, when growing spring wheat of the "Zlata" variety in vessels under phytotron conditions.…”

The article presents the results of a field vegetation experiment in the Rostov region on the cultivation of spring wheat of the “Zlata” variety with the use of an environmentally oriented organic mineral fertilizer from liquid waste of pig farms by the method of split plots with a randomized placement of variants in repetitions, the repetition of the experiment is three-fold. The agrochemical indicators of the soil before and after wheat cultivation at the horizons of 0-20 and 20-40 cm are given. The scheme of carrying out the experiment, including different doses of organic mineral fertilizer application and a plan for cutting plots, is indicated. During the growing season, constant observations of the plants were carried out together with the care. The dynamics of the growth of wheat biomass in different periods of time from planting and its yield are presented. The influence of different doses of ecologically oriented organic mineral fertilizer from pig manure on the yield of spring wheat is estimated. According to the results of experimental data, the effective dose of organic mineral fertilizer application from pig manure was established-2t/ha. The yield of grain crops (wheat) per hectare was determined-49.2 c / ha. The spring wheat variety “Zlata”, which is unusual for the Rostov region, gave a high yield when applying an environmentally oriented fertilizer, which proves its value both in agronomic and ecological terms. The absence of toxic effects on the soil of organic mineral fertilizers for heavy metals (copper, nickel. cadmium, lead), an increase in humus from 5.43% to 5.52%. The assessment of the nutrient reserves in seeds and the effect of organic mineral fertilizer doses on the quality of spring wheat grain of the «Zlata» variety is given. The highest amount of gluten-40.03% - was observed when using the fertilizer at a dose of 2 t / ha.
